hope im not to late sorry got distracted by phone
Probability of getting two reds:
Probability of one red = 4/9
Probability of second red = 3/8
=> 4/9 X 3/8 = 12/72 = 1/6
Probability of getting blue then red:
Probability of one blue = 5/9
Probability of second ball red = 4/8
=> 5/9 X 4/8 = 20/72 = 5/18
Brings me back to my 11plus days.
Hope the answer is 1) 12/72 16.6% and 2) 20/72 27.7%
